Abstract

The invention provides a new method for synthesizing a particle reinforced metal-based composite material under the coupling effect of the pulsed electric field and the electromagnetic field, belonging to the technical field of material preparation. The method is mainly characterized in that the pulsed electric field and the electromagnetic field are applied to melt in the synthetic process of preparing the particle reinforced composite material through the traditional direct melt reaction method; the current peak density of the pulsed electric field is 0.1-10A / cm2; the pulse frequency is 0.1-10Hz; the applied electromagnetic field is the low-frequency alternating electromagnetic field; the electromagnetic parameters are as follows: the frequency is 1-50Hz and the working current is 1-1000A; the magnetic induction of the melt center is controlled between 0.01T and 1T; and the time for treating the melt by the pulsed electric field and the electromagnetic field is 3-10 minutes. The method has the following beneficial effects: the synthetic reaction rate and yield can be obviously improved; and the method has obvious effects on controlling the particle morphology and promoting dispersion and is suitable for preparing the high-performance particle reinforced composite material in industrial scale.
